Math Lesson 3.2



Today we related addition to multiplication.  Students used their iPads to group items and write an addition sentence for the groups.  We followed up by writing a multiplication problem to match.  Please note that in the above example, the first factor in our multiplication problem (the 4) is the number of groups, and the second factor in the problem (the 3) is the number of items in each group.  It is very important that the correct order is used.  Although 3x4 is also 12, our picture shows 4x3.  The addition and multiplication sentences need to match the picture.
